Other then the size are not these two more or less the same? In my opinion the Explorer looks more like an Air-King II then an Explorer II

Besides this you also got the Oyster Perpetual watch, that also more or less looks just the same as an Air-King other then the size.

So what is the difference of these watches other then the dial hands and size? Do they not all got the same functions? Could they not all just be Air-King with different dials and hands, like the datejust, and could not the watches with a larger size just be Air-King II, just like the Datejust II?

I miss more 36-40mm watches from Rolex that are just plain elegant watches with a beautiful dial that shows the time. No date function, day function, GMT functions, rotating bezels and so on. Just the time like those on the photos over does.

I do not know why but I just started wondering and thinking about this.
